LLM development services for real business work
Large language models can read, summarize and draft, but on their own they don't know your business. Raileon builds LLM applications that are grounded in your documents and connected to your tools, with rules for what they can and can't do.
We don't train foundation models. We pick the right model for each job, build the application around it, test it on your real work and run it for you.

What we build with LLMs
- Document understanding. Pull fields, totals and clauses out of invoices, contracts, forms and emails.
- Knowledge assistants. Answers from your own policies and records, with the source shown.
- Drafting. First drafts of replies, proposals and reports for a person to approve.
- Sorting and routing. Read incoming requests and send each one to the right person or system.
How we keep LLM applications reliable
- Grounded in your approved content, not the open internet.
- Tested against real examples from your team before launch.
- Approval rules for anything customer-facing.
- Your data is never used by us or our AI provider to train AI models.
